There are many good reasons why a Jewish woman should shave her head when she marries. One explanation is that, during mikvah, water must touch every part of the woman's body. If the hair is knotted, water might not touch everything, and would render the mikvah invalid. So, best to shave completely!

"St. Valentine's Day, as we know it today, contains vestiges of both Christian and ancient Roman tradition."

"One legend contends that Valentine was a priest who served during the third century in Rome. When Emperor Claudius II decided that single men made better soldiers than those with wives and families, he outlawed marriage for young men—his crop of potential soldiers. Valentine, realizing the injustice of the decree, defied Claudius and continued to perform marriages for young lovers in secret. When Valentine's actions were discovered, Claudius ordered that he be put to death."

"While some believe that Valentine's Day is celebrated in the middle of February to commemorate the anniversary of Valentine''s death or burial—which probably occurred around 270 A.D—others claim that the Christian church may have decided to celebrate Valentine''s feast day in the middle of February in an effort to ''christianize'' celebrations of the pagan Lupercalia festival."

The people of Israel are called upon to contribute fifteen materials—gold, silver and copper; blue, purple and red-dyed wool; flax, goat hair, animal skins, wood, olive oil, spices and gems—out of which, G-d says to Moses, "They shall make for Me a Sanctuary, and I shall dwell amidst them."

On the summit of Mount Sinai, Moses is given detailed instructions on how to construct this dwelling for G-d so that it could be readily dismantled, transported and reassembled as the people journeyed in the desert. (from Chabad.org)
